Cocktail Ring n°1, Gold, Diamonds

Sixteen diamonds illuminate its delicate structure and enhance its signature pavé setting.

Inspired by the diatom Coscinodiscus Oculus Iridis, the ring reveals the dazzling forms of the ocean’s microscopic living world, while evoking a constellation of stars.
Bespoke jewellery, handcrafted in Paris
Made to order and entirely handcrafted in Paris, the Cocktail Ring I can be personalised through the choice of gold and the precious or fine gemstones that adorn it. It is also available in colourful gemstone compositions, allowing each ring to become a deeply personal creation.
A complimentary resizing service is included to ensure the perfect fit.
The ring is created in our Parisian workshops, renowned for their exceptional craftsmanship and whose expertise is also sought by some of France’s most prestigious jewellery maisons.
Upon request and subject to a feasibility assessment, a bespoke quotation can be prepared to give new life to the gold from an existing 18-carat gold jewel.
Infused with light and emotion, the Cocktail Ring I is a jewel to cherish, give or pass down. It carries within it the spirit of Sœur & Mer: the beauty of craftsmanship, the strength of connection and the optimism of creation.
